Do you have a recent good backup? Not of DATA_300, the backups are failing because backup exec is set to skip if a consistency check fails. I guess I could run a backup withing SQL mgr itself. I'm just a consultant here but they don't have anyone else to look at it.

Did you recently run out of disk space or have a hardware failure/server crash? No, could have been a power failure nobody told me about but otherwise no failures.

Did you recently apply a service pack and run out of space whole doing it? No
